摘要： In an exposure apparatus of the invention, for a spatial light modulator, each of a plurality of pixel portions fewer than the total number of the pixel portions is controlled with a control signal generated according to exposure information. Namely, a part of the pixel portions is controlled without controlling a whole of the pixel portions on the substrate. Thus, the number of pixels in the pixel portions is decreased, and transfer time of the control signal becomes short. This enables modulation speed of the laser beam to be increased and the high-speed exposure to be performed. An incorporated laser light source, in which the laser beams are incorporated and struck on the optical fiber, is preferable to the laser device. By adopting the incorporated laser light source, high brightness and high output can be obtained, and it is preferable to the exposure of the spatial light modulator. Since the fiber array is obtained with few optical fibers, it is low cost. Since the number of optical fibers is few, the light-emitting region is further decreased when the optical fibers are arrayed.

摘要： The invention provides an exposure device that can conduct digital exposure with high precision and with a high light-use efficiency using evanescent light. Light that is modulated by a DMD and condensed by a microlens array is incident at corresponding optical fiber cores arranged in a matrix in an evanescent array head, and is guided through the insides of the optical fibers. Because the light condensed by the microlens array is incident at the optical fiber cores corresponding to the microlenses, the light can be efficiently incident. Evanescent light leaks out from micro-openings formed in emission-side end portions of the optical fibers, and a photosensitive material is exposed by this evanescent light.

摘要： An optical fiber of a bundled fiber light source is an optical fiber whose core diameter is uniform but whose emission end cladding diameter is smaller than an incidence end cladding diameter thereof, and a light emission region thereof is made smaller. An angle of luminous flux from this higher luminance bundled fiber light source, which passes through a lens system and is incident on a DMD, is smaller, i.e., an illumination NA is made smaller. Thus, an angle of flux which is incident on a surface that is to be exposed is smaller. That is, a minute image formation beam can be obtained without increasing the image formation NA, focal depth is lengthen.

摘要翻译：在本发明的曝光装置中，对于空间光调制器，利用根据曝光信息生成的控制信号来控制少于像素部分总数的多个像素部分中的每一个。即，在不控制基板上的整个像素部分的情况下，控制像素部分的一部分。因此，像素部分中的像素数量减少，并且控制信号的传送时间变短。这使得能够增加激光束的调制速度并执行高速曝光。其中激光束并入并撞击在光纤上的并入的激光光源优于激光装置。通过采用所结合的激光光源，可以获得高亮度和高输出，并且优选空间光调制器的曝光。由于光纤阵列获得的光纤很少，所以成本低。由于光纤的数量少，所以在配置光纤时，发光区域进一步降低。
